Noisey M60 after hard use

[Sidney Rough-Diamond]

As some of you will have read,I took my 540 to the Nurburgring at Easter. After a 13 mile lap, the engine was very 'tappy' after this. Same thing after just a couple of sideways laps of the local roundabout. Give it a min and it all goes quiet again and runs fine. Any ideas ?

sticky valves? throw some fuel injector cleaner in there.

What kind of oil are you using?

[winfred]

the oil pump is probably in the process of falling off and it's sucking air, takes a couple minutes for the lifters to burp

[Tiger]

That's right... I forgot about that...

better tighten that **** up. I had one bolt in the pan and the other hand loose and it came off the first time I changed out tranny fluid.....

zactly what that is, specially on left hand sweepers
